I’ve seen this error before it’s caused by missing Nango config for Google Calendar in your VAPI setup, not because Google Calendar is unsupported. You need to properly configure your Nango provider credentials (client ID/secret, redirect URIs, scopes) and link them in your VAPI project before the calendar tools will work. I can help you fix the integration step‑by‑step so your AI Assistants can check availability and create events reliably. @James newbie
